MASSAGE INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 749,690, dated January 12, 1904.

Application filed May 16, 1903. Serial No. 157,475. (No model.)

have been objectionable to the patients, and

it has been necessary oftentimes to ultimately resort to the use of the hand for massaging the afflicted parts.

One of the objects of my invention is to provide an instrument which can be attached to the hand of the operator to permit the vibrations to be transmitted therethrough to the body of the patient, thereby overcoming the objectionable violent impacts upon the body without at the same time necessitating the usual fatiguing movements of the hand of the operator.

Another object is to so construct the instrument as to permit it to be applied directly upon the parts to be treated when it is deemed desirable.

A further object is to produce an oscillating vibrator adapted to be operated by attaching the instrument to a suitable source of electricity.

Another object is to employ means readily accessible and operated whereby the number of strokes or impacts by the vibrator in a given period may be regulated.

With the above and other objects in view the invention consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of my improved Fig. 2 is an end'elevation thereof.

Fig. 3 is a side elevation showing the handle removed and a strap in position for holding the device upon the hand of the operator.

Fig. 4 is an end elevation of the vibrator with the parts in the position illustrated in Fig. 3. Fig. 5 is a side elevation of my improved vibrator, showing one of the tapping devices in position thereon. Fig. 6 is a similar view showing a modified form of tapping device connected thereto. Fig. 7 is a top plan view of the vibrator with the handle and the connecting-wires removed. Fig. 8 is a bottom plan View of the device. Fig. 9 is a detail view of the circuit-closing plugs. Fig. 10 is a longitudinal section through the casing and showing the interior mechanism of the device in elevation. Fig. 11 is a plan view of the mechanism removed from the casing. Fig. 12 is a similar plan view with the armature removed. Fig. 13 is a bottom plan view of the armature, and Fig. 14 is a diagrammatical View showing the various circuits through the mechanism of the vibrator.

Referring to the figures by numerals of reference, 1 is a substantially rectangular casing formed of any suitable material and having headed lugs 2 at the ends thereof. The bottom of the casing is adapted to be closed by a curved plate 3, which is held in closed position by means of screws 1, adapted to engagea cross-bar 5, which extends transversely of the casing and is secured to the sides thereof by meansof screws 6 or other suitable devices. The heads of these screws are adapted to project a suflicient distance through the sides of easing 1 to permit a fork 7 to be sprung thereover. A handle 8 is secured in any suitable manner to the center of this fork, and one of the arms of the fork has an aperture 9 therein, the opposite edges of which are protected by plates 10 of insulatingmaterial.

Secured upon the top of casing 1 at the center thereof and between the arms of the fork 7 is acylindrical block 11, preferably formed of insulating material and having a stem 12 mounted in the center thereof and provided at its upper end with a milled nut 13, by means of which said stem can be readily rotated. Secured to this nut is an index or finger 1 1, which is adaptedto be moved in position over any one of a series of graduations formed I screw 20, while the other thimble, 19, is electrically connected by means of a screw 21 with a forked plate 22, mounted on said screw. This plate, as well as the screw 21, is insulated from casing 1, as clearly illustrated in Fig. 10. The thimbles 18 and 19 are adapted to receive split plugs '23 and 24, respectively, which extend from a block of insulating material, and extending into this block are two wires 26 and 27 of an electric circuit, one wire, 26, being connected to plug 23, while the other wire is connected to the plug 24. The block 25 is 'adaptedto be inserted into the aperture 9, hereinbefore referred to, so as to bring the plugs 23 and 24 into position within their respective thimbles 18 and 19, and when in this position the said block will lock the fork 7 against movement upon the holding-screws 6.

Magnets 28 and 29 are secured to and extend from opposite sides of the cross-strip 5, hereinbefore referred to, and an anvil 30 is formed integral with the core of each of these magnets and is so shaped as to bear snugly upon the inner surface of plate 3 when the same is in position upon the casing. Each of these anvils has a shoulder 31 thereon, which is arranged within the path of an arm 32. Two of these arms are provided, one being arranged at each end of an armature 33, and this armature is pivoted at the center between arms 34, extending upward from the ends of a strip 35, and screws 36 extend through these arms and engage the opposite sides of the ar-' mature and act as bearings therefor. The strip is slidably mounted between the magnets 28 and 29, and the stem 12, hereinbefore referred to, has a threaded portion 37, which extends through the center of strip 35 and engages the same. Stem 12 is swiveled in crossstrip 5, and it is therefore obvious that when the same is turned the armature will be raised or lowered from or toward the magnets. Strips 38 are arranged parallel to but insulated from each other at one side of the magnets 28 and 29, and each of these strips has a contact-screw 39 extending upward therefrom. These contacts are arranged under the opposite ends'of a spring-strip 40, which is mounted upon plates 41, extending laterally from a rocking strip 42. The two strips 40 and 42 act as circuit-closers, and the springstrip 40 is adapted to be brought into position upon either of the contacts 39 by laterallyextending lugs 43, arranged upon the arms 32 of the armature and adapted to come into contact with ears 44, extending from the ends of strip 42. It will be understood, of course, that the rocking strip 42 and spring-strip 40 are electrically connected to the cross-strip 5, and as said strip is fastened to the casing 1 by means of screws 6 it will be understood that a current of electricity will be free to pass from plug 23 to thimble 18, screw 20, and casing 1 to the strips 40 and 42. A wire 45 extends from the forked plate 22 and connects the same to the twomagnets 28 and 29, and

the contacts 39 are, asillustrated in Fig. 14,

connected by means of wires 46 and 47 to the oppositely-arranged magnets. Shunt-wires 48'connect wires 46 and 47, respectively, to the anvils 30. -A spring 49 is fastened to one of the pivot-screws 36 and extends under the armature 33 and serves to hold the springstrip 40 of the circuit-closer normally in position upon one of the contacts 39.

It will. be understood. that when thewires 26 and 27 are connected toa suitable source of electricity the current will pass through wire 26, thimble 18, and screw 20 to casing 1 and thence into the rocking strip 42 and the spring-strip 40 of the circuit-closer. From here the current will pass through the wire 46 into magnet 29 and energizing the same will attract the adjacent arm 32 of the armature thereto, thereby electrically connecting strip 40 with the other contact 39 and breaking the connection first established. As soon as this connection is made the current will pass from strip 40 into wire 47 to magnet 28, thereby energizing the same and returning the armature to its initial position. By means of the revoluble stem 12 the armature 33 can be moved from or toward the magnets a suitable distance, and in this way a desired number of vibrations to the minute may be obtained and the force of the impact regulated.

When it is desired to apply the instrument directly to the parts to be massaged, the curved bottom plate 3 may be, if convenient, placed thereon, and the oscillation of the armature caused by the current passing through the magnets will cause the arms 32 to rapidly hammer on the anvils 30, and vibration thus produced will be transmitted through said anvils and plate 3. Where it is not convenient to apply the curved plate to the part to be treated, the spring-forked tapping device 50, having outwardly-extending ends 51, may be inserted into slots 52, formed in the bottom plate 3 directly under anvils 30, and to the center of this rod is fastened a stem 53, having a ball 54 at the end thereof adapted to be placed in contact with the part to be treated. In Fig. 5 I have shown this form of attachment, and in Fig. 6 I have shown another modified form consisting merely of a straight rod 55, having a ball 56 at one end and its other end being adapted to be screwed into an aperture 56, formed within the center of the plate 3. I have shown the rod 55 provided: wvith a milled nut 57, by means of which the same may be readily rotated. 7

As hereinbefore stated, the direct application of the vibrations to the body of the patientis often objectionable, land in such cases the attachments illustrated in Figs. 5 and 6 may be dispensed with and a strap 58 secured longitudinally over the curved plate 3 in any suitable manner. shown this strap arranged within slots 59,

formed, within plates 60, having buttonhole= In Figs. 3 and 4 I have slots 61 therein adapted to receive the headed lugs 2, hereinbefore. referred to. of this strap 58 the vibrator can be securely fastened upon the backof the hand of the operator, and when used inthis manner the hani and by moving the hand over the part to be treated or massaged .the vibrations caused by. the oscillating armature will be transmitted through the hand and the power thereof materially diminished.

It will be seen from theforegoing description that the device is extremely simple and inexpensive in construction, .andby means thereof it is unnecessary to apply the vibra vantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.
